[2020 - 2021] BSc - Markéta Machalová : Detection of Varroa destructor using computer vision

Department of Algebra, Faculty of Mathematics and Physics, Charles University

Abstract: The bachelor thesis deals with the design and description of a tool that can simplify the process of monitoring varroosis. Using image processing methods, it detects individual mites from the picture of the bottom board in the beehive. For better image resolution we used several images from one bottom board. Those images were then stitched into one image using image registration. In the first part we focused on the use of classical image processing methods that can detect varroa only on the basis of the approximation of the body of the mite with a parametrically descriptive curve. In the second part we used a more powerful convolutional neural network. During each of the 500 training epochs we saved the parameters of success. Finally, we inserted a test data into the trained network and compared it with expected outputs. The thesis contains a theoretical description of algorithms and methods, their use in our detector, and interpretation of results.

[2020 - 2021] MSc - Kajetán Poliak : Hand pose estimation during car driving

Department of Mathematics, Faculty of Nuclear Science and Physical Engineering, Czech Technical University in Prague

Abstract: Hand pose estimation plays a fundamental role in human computer interactions, moreover it allows us to analyze human behavior. The problem is nontrivial due to complicated hand variations caused by complex articulations, self-occlusions or shape, size and color ambiguities. We provide complex proposal of different detection and pose estimation methods and their evaluation. The comparison of deep map and RGB based pose estimation is provided and applied to real-life data from the driving simulator. Furthermore we design an annotation tool for RGB-D data which we used to produce a test dataset.

PROVENANCE - PROviding VErificatioN AssistaNCE for New Content

[2018 - 2021] H2020-EU.2.1.1. : 825227

Objectives: PROVENANCE will develop an intermediary-free solution for digital content verification that gives greater control to users of social media and underpins the dynamics of social sharing in values of trust, openness, and fair participation. Specifically, PROVENANCE will use blockchain to record, in a secure and verifiable manner, multimedia content that is uploaded and registered by content creators or identified for registration by the PROVENANCE Social Network Monitor. The PROVENANCE Verification Layer will apply advanced tools for multimedia analytics (semantic uplift, image forensics, cascade analysis) to record any modifications to content assets and to identify similar pieces of content. A personalised Digital Companion will cater to the information needs of end-users. To help consumers navigate content and develop digital literacy competencies, an iconographic Verification Indicator will contextualise individual pieces of content with relevant information including when the content was registered, by whom, and any subsequent transactions. PROVENANCE will be co-created with diverse representatives of civil society across four distinct use-cases in the social media domain (citizen information seekers, citizen prosumers, factual content creators, and creative content creators). However, the findings will be applicable to any area in which social media and verification are important. The scientific and pragmatic insights gained through PROVENANCE will significantly advance the state of the art in intermediary-free solutions for content verification, understanding of information cascades and information sources on social media, the openness of algorithms, and user control over personal data. In so doing, it will lay the foundation for a new federated social network grounded in trust, openness, and fair participation. In addition, it will support the development of an observatory on information veracity and social media best practice under the ICT28 CSA.

Automatic evaluation of videokymographic recordings for early diagnosis and prevention of vocal fold tumors

[2014 - 2017] Technology Agency of the Czech Republic : TA04010877

Objectives: The goal of the project is to develop a sophisticated software for videokymography (VKG) which will enable automatic evaluation of medical videokymographic recordings of vibrating vocal folds and arrive at correct medical diagnosis. Further goal is to develop a certified method of VKG evaluation to be used in clinical practice. VKG camera is an existing device which was developed in 1994 in collaboration of Czech and Dutch colleagues. It has been used for diagnosis of vocal fold vibration problems caused by various voice disorders, the most serious being vocal fold cancer. Currently, evaluation of VKG recordings can be done only by a highly experienced clinician. The evaluation is complicated and time-consuming. Therefore the method has not been widely used. Addition of a software for automatic evaluation will allow wider, more efficient and less time-demanding application of the method in clinical practice and an early and rather inexpensive diagnosis of tumorous states. It will allow detecting vocal fold cancer at an early stage when the treatment can be done noninvasively or by a simple surgical intervention so that the quality of life is preserved. The project is based on collaboration of four partners: clinical centre specialized in diagnosis and treatment of voice disorders (Voice Centre Prague, Medical Healthcom, Ltd), team of the inventor of the method of videokymography (dr. Svec, Department of Biophysics, Palacky University Olomouc), research institute specialized in digital image analysis (Institute of Information Theory and Automation, Academy of Sciences of the Czech Republic) and a company experienced in diagnostic product development (STARMANS electronics).
